Thank you! You helped me pass my abstract algebra class where our teacher just assumed we all knew how to write proofs and threw a ton of material at us. You’ve allowed me to enjoy pure math again!

3:58 “because.. I just.. I can’t even” don’t be silly guys. Let’s not disappoint her. She’s my guardian angel this semester♥️. Make sure you’re up to speed with the basics. 😂

You are less confusing than most videos about math proofs. Thank you for sharing your knowledge and teaching abilities.

Lmao I was working ahead, and around 3:55, I had just finished writing n^2 = 4k^2 + 1 thinking I was a god. Then, I heard Dr. Brehm say "Pleaaasee do not give me 4k^2 + 1... because.. I just can't even" and I felt personally attacked 😂

Your videos are incredibly helpful. I'm taking this class online and all they give us is a textbook. This has been a wonderful supplement. And the "I can't even" comment had me in fricken tears. :lol:

Oh goodness! A teacher who explained the material instead of posturing how smart they are?!? You might just be my favorite person.

(2k + 1) (2k + 1), if you multiply them together, you get 4k^2 and 4k + 1
